Ball Mill
Technical Advantage:
Ball mill consists of feeding, discharge, turn, transmission (reducer, gear, motor, electric control) and other major parts. Hollow shaft adopts steel castings, lining can conversion, the slewing gear with cast roll teeth processing, cylinder body, wear resistant lining board with good abrasion resistance.The machine is stable operation and reliable performance. According to the row material and mineral, can choose dry grate ball mill and wet grate ball mill.
Operating principle:
The level of ball mill is a cylinder, out of the hollow shaft grinding and top parts, cylinder for long cylinder, equipped with grinding medium in the cylinder, cylinder for steel manufacturing,steel plate and cylinder are fixed,the grinding medium is commonly steel ball, and according to different diameter and a certain proportion in tube, steel grinding body can also be used According to the particle size of grinding material,the material is mill feeding the hollow shaft in cylinder body, when the ball mill simplified turning, grinding body effect by the inertia and centrifugal force, the effect of friction make it for cylinder liner board near being carried away by cylinder, when was taken to a certain height, cast by its own gravity and whereabouts of the grinding medium like projectile body of the cylinder body material to break. Material through feeding device by filling hollow shaft spiral evenly into first warehouse, the warehouse has ladder lining board or corrugated lining board, with different specifications inside steel balls, cylindrical turning generate centrifugal force brought steel ball to a certain height then falling to generate critical and abrasive materials. Materials in the warehouse after reaching coarse grinding, the single warehouse plate into the warehouse, the warehouse with flat inside lining board, there are steel ball, will further grinding material. Powder through the unloading board to finish grinding operation.Cylinder in the process of turning, grinding body also have slipped phenomenon,in the process of slide with abrasive to the material, in order to effectively use the grinding to teach the material particle size of 20 mesh mill, the mill cylinder body with every storehouse board space into two parts, namely become double warehouse, materials into the warehouse by steel ball break, material into the storehouse, the steel material for grinding, fine grinding of qualified materials from the discharge end hollow shaft discharge, feeding of small particle materials for mill, such as sand no.2 slag, crude ash, mill barrel can set partition, become a single warehouse cylinder grinding, grinding volume can also be used for steel.This machine is horizontal cylindrical rotating device, outside is the gear transmission,two warehouse, grate ball mill.Material through feeding device by filling hollow shaft spiral evenly into first warehouse, the warehouse has ladder lining board or corrugated lining board, with different specifications inside steel balls,cylindrical turning generate centrifugal force brought steel ball to a certain height then falling to generate critical and abrasive materials. Materials in the warehouse after reaching coarse grinding, the single warehouse plate into the warehouse, the warehouse with flat inside lining board, there are steel ball, will further grinding material. Powder through the unloading board to finish grinding operation.
Application: It will be widely used in cement, Silicate Products new building material, refractory material, fertilizer, black and nonferrous metal mineral processing and glass ceramics industry, etc
Material: Quartz, feldspar, iron ore, manganese, copper ore, silica, etc.
